Filter by:The purpose of this study is to evaluate the adequacy of zoledronic acid in maintaining bone mass after two years of treatment with Forteo, in postmenopausal women.
To confirm the non-inferiority of 75 mg risedronate tablets taken on 2 consecutive days per month as compared to 5 mg risedronate tablets taken daily in increasing bone mass in lumbar spine in postmenopausal women with osteoporosis. To confirm the efficacy of 75 mg risedronate tablets taken on 2 consecutive days per month in postmenopausal women with osteoporosis in increasing bone mass in proximal femur, femoral neck and femoral trochanter and decreasing bone resorption. To confirm general safety of 75 mg risedronate tablets taken on 2 consecutive days per month as compared to 5 mg risedronate taken daily.
The primary aim of this study is to determine the effects of supplementation with both calcium and vitamin D on changes in bone density of the hip in men and women age 65 and older.
There is increasing evidence that the acid-base balance of diet plays an important role in the health of bones and muscles. An excess of acid in the body can result in calcium loss and muscle breakdown. Potassium bicarbonate, a base supplement, can neutralize acid within the body. The purpose of this study is to determine the effectiveness of potassium and bicarbonate, alone and combined, at reducing bone loss and preventing muscle wasting in older adults.
RATIONALE: Learning about the effect of exemestane and anastrozole on bone mineral density in postmenopausal women with primary breast cancer may help plan treatment, decrease the risk of broken bones, and help patients live more comfortably. PURPOSE: This phase III trial is studying bone mineral density in postmenopausal women with primary breast cancer who are receiving treatment on clinical trial CAN-NCIC-MA27.
To confirm the superiority of 5 mg daily risedronate as compared to placebo in maintaining or increasing bone mass in lumbar spine in osteopenic postmenopausal women To confirm the efficacy of 5 mg daily risedronate in osteopenic postmenopausal women in maintaining or increasing bone mass in proximal femur and decreasing bone resorption To confirm general safety of 5 mg daily risedronate as compared to placebo
This study is designed to test whether calcium supplementation alone or calcium plus vitamin D reduces the incidence of fractures, reduces high parathyroid secretory activity, and halts bone loss in a population-based sample of women 55+ years of age. - A calcium supplement of 1400 mg/d will significantly reduce the cumulative incidence of spine and appendicular fractures over four years for independently living, rural women 55 years of age and older compared to similar women on their usual diets. - A calcium supplement of 1400 mg/d plus 1100 IU vitamin D/d will significantly reduce the cumulative incidence of spine and appendicular fractures compared to a calcium supplement only.
Extreme magnesium deficiency is known to have an impact on the synthesis, secretion and/or action of calcium regulating hormones. Many older adults are at risk for less severe magnesium deficiency, since the majority of adults receive less than the Recommended Daily Allowance of magnesium. We hypothesize that magnesium supplementation will have a beneficial effect on calcium regulating hormones and markers of bone turnover.
The primary objective of this study is to compare risedronate 35 mg and placebo with respect to the percent change at 12 months for distal radius trabecular bone volume (BV/TV) in osteopenic postmenopausal women, as measured by three-dimensional peripheral quantitative computed tomography (3D pQCT). The secondary objectives are to compare the percent change from Screening/Baseline between the 2 treatment groups for the following measurements: - Bone mineral density of the lumbar spine, femoral neck, femoral trochanter, and total proximal femur using a dual energy X-ray absorptiometry (DXA) scan at 12 and 24 months; - 3D pQCT analysis of distal radius and distal tibia bone microarchitecture data at 6, 12, and 24 months; and - Bone turnover markers (BTMs) of: - fasting serum carboxyterminal cross linking telopeptide of type 1 bone collagen (CTX 1); - serum aminoterminal propeptide of type 1 procollagen (PINP); and - urine N-telopeptide cross-links (NTX) at 3, 6, 12, and 24 months.
The purpose of the study is to determine if daily teriparatide reduces back pain more effectively than weekly risedronate in women with osteoporosis who have chronic back pain due to a spinal bone fracture.
